Top 7 Pool Heaters Buyers Guide For 2023
What is a Pool Heater?
Just like you need hot water for showering, doing dishes or laundry, you might also need hot water for your swimming pool. Since you cannot use your regular hot water heater for swimming pool, you will need a special pool heater.
These are ideal for people who live in colder areas and want to extend swimming season by a few more weeks or even months.
Water temperature your desire, the size, type and even brand of your pool can dictate the best type of heater. Buying the ideal heater can be tricky.
Choosing a heater that is too powerful for your pool can cost you a lot more in terms of monthly bills as well as initial cost. Likewise, using a smaller heater could be an absolute waste of money because it wouldn’t raise the water temperature to your desired level.
The Best Type of Pool Heater:
There are several different types of pools. Each has its own merits and issues. Let’s quickly review all of them before reviewing the top-rated items.
Solar Pool Heater:
Just as the name suggests, this heater utilizes solar panels to capture energy from the sun and transfers it into your pool. These heaters work pretty slowly, and heavily depend on how bright the sun is.
Their initial cost can be very high. But then there is no monthly cost, as well as little to no maintenance cost. Moreover, solar pool heaters are the best in terms of eco-friendliness.
Who are they ideal for?
They are ideal if you live in a sunny part of the world and can afford to install expensive equipment that will last longer and save you money over time.
Electric Pool Heater:
These heaters run off of your electric connection. They are extremely fast and can offer quick heat up year round.
Who are they ideal for?
They are ideal if you can afford to pay higher electricity bills, but want your pool to heat up quickly.
Electric Pool Heat Pump:
These are innovative heaters that run off of your electric connection. However, they don’t produce heat but move it from the air in the surroundings to your pool. They are very long lasting and don’t increase your electricity bill by much.
Who are they ideal for?
They are ideal if you live in an area where the outside temperature stays above 40. They become less efficient in colder weather.
Natural & Propane Gas Heaters:
These heaters used to be very popular in the past. The increasing gas prices have decreased their demand nowadays.
They use propane or natural gas. As the pump circulates water in the pool, it passes through the filter and then to the heater. The gas is burning in the heating chamber, and energy is transferred to the water. This water becomes hot and is then sent back to the pool.
Who are they ideal for?
They are usually the cheapest option when it comes to initial cost but cost more over time. That’s why they are ideal if you need a heater very infrequently.
How to Choose the Best Pool Heater?
To choose the ideal heater for your pool, keep these things in mind:
Choose the Right Size
First, you need to find out the surface area of your pool. If you know how many gallons of water it has, that also works. Once you have this info, you can get a pool that yields enough heat.
The power of a heater is measured in BTUs (British Thermal units). Here is a table to help you find an optimal heater for the size of your pool.
Consider How Fast You Need Your Pool to be Ready?
If you want your pool to get heated in a short time, you should look for a high power electric heater. If speed doesn’t matter, but you want to save some money on the monthly bill, solar could be the right choice.
What’s Your Budget?
For pool heaters, there is an initial cost, and then there is a monthly bill. Usually, there is a tradeoff between the two.
Gas heaters are usually the cheapest, some costing around $1,000 while solar can be anything upwards of $3,000. Don’t forget the installation cost on top of it. However, in the long run, the solar will cost nothing, but gas heater might cost you up to $500 every month.
Size and Shape of Pool:
Size and shape of the pool will also dictate the ideal type and power of your heater. Needless to say, larger and complex shaped pools will need a more powerful heater and vice versa.
Heaters for InGround Pools Vs. Above Ground Pools:
The best heater for in-ground pool might not be a good choice for above ground pool. For instance, solar heaters are not ideal for in-ground pools because of their low power. On the flip, a powerful electric heater could be a huge waste of money for a small above ground pool.
How do Pool Heaters Work?
Did you ever wonder what is underneath the hood of your pool heater? Or how it works?
If yes, here is the short answer
Different types of pool heaters work differently. We have briefly touched on their functionality in the previous sections, here is a quick explanation of the general principle most pool heaters are designed on.
To understand how a pool heater works, we need to understand the function of each of its different parts.
There is a water intake that sucks the water into the heater. There is a control panel that connects to the thermostat and allows you to regulate the temperature.
Underneath the thermostat, there is control module, which is actually a circuitry that transfers messages between the thermostat and other parts of the heater such as the igniter.
Depending on the type of the heater, there could be gas input and gas valves or electric cable that provide the heater power. Moreover, there can be burners or heat exchangers.
The heat exchanger is usually wrapped around the tube through which the water flows. When water flows through the tube, heat is transferred from the burner to water. Normally there is a switch to control the flow of water as well.
Once heat is transferred to the water, it’s pushed out back to the pool.
Little-Known Benefits of Pool Heaters:
Depending on the type of the pool heater such as electric or gas or heat pump, there are specific benefits to each type. However here are some common benefits:
Your Swimming Season Gets Extended:
Swimming pools are expensive, and most pools have a finite lifespan which can range between 3 and 15 years. However, you can only use your pool in certain months of the year because of the weather. This means that in areas with prolonged winter, your swimming pool will be used for only a few months every year.
In other words, you won’t be able to get the most out of it before it reaches its end of life.
This is where the pool heaters can extend your swimming season by heating your pool water to a comfortable temperature level. While a pool heater might not work in extreme winter, it can definitely improve the water temperature in fall and autumn.
In the areas where winters are mild, you can extend your swimming season to last the whole year. This definitely gives you the best bang for your buck you invested in your pool.
You Can Swim Even During the Night:
In warmer areas, swimming at night might not be an issue. However, in certain areas, the water temperature can drop drastically in the evenings even when the day was fairly warm.
This means your pool will be simply unusable during the night.
But what If you want to use your pool for an overnight party or family gathering? Or maybe you want to do some cardio workout early morning?
Again the pool heater can regulate the temperature and allow you greater flexibility regarding the time of the day in the evening you can use your food.
Better Health:
What some people don’t know is that swimming in warmer water can be better for your health.
Swimming is a great aerobic exercise. It’s especially ideal for those who have joint issues. However, swimming in cold water can cause chilling. This can have adverse effects on those who have a weak immune system such as children, people with arthritis, or older adults.
Your pool heater not only counters this effect but also offers therapeutic benefits by helping loosen the stiff joints and relax sore muscles.
Pool Heater vs. Heat Pump:
Pool heat pump and electric heater both run on electricity, however, they are totally different.
Electric heater has a conventional way of generating heat from electricity by transferring heat from a hot coil into the water.
On the flip, the pool heat pump generates heat from the air in the surroundings and transfers it into your pool water. The only thing a pool heat pump requires electricity is to run air compressor and other components.
The initial cost of a pool heat pump might be more than that of an electric heater, but it can cost up to five times less than a gas or electric heater in terms of monthly cost. That means, in the long run, you’ll be saving a lot more.
With proper installation and maintenance pool heat pumps can last up to 10 years or even more. This is considerably longer than their rivals i.e., gas heaters as well as electric heaters.
Electric heaters are less expensive but cost more in terms of electricity bills. However, they have a smaller footprint and can also be used in indoor spas.
Depending on your needs, you may choose one or the other. However, some people use both. They use gas or electric heaters for indoor pools or in winter and heat pump in autumn or fall.
Conclusion:
After a pool filter system, the heater is definitely the best accessory for your swimming pool, no matter you have an in-ground or above ground pool.
It not only extends your swimming season but also helps get more value out of your swimming pool. Moreover, it makes swimming a lot more fun and healthy experience.
Now you know what is the best pool heater for your pool. Keep in mind all the above-mentioned tips and tricks when shopping for the pool heater. Thanks for taking the time to read our Top 7 Pool Heaters Review Guide For 2023.
